Primary Outcome Measures:
- Apathy [ Time Frame: at baseline ]The Frontal Systems Behavior Scale. Raw scores are converted to T-Scores using published norms. T-Scores have a mean of 50 and a standard deviation of 10. T-scores less than or equal to 64 are within average range. T-scores equal to or greater than 65 are indicative of a clinically significant problem. Higher scores indicate greater problem severity.
- Apathy [ Time Frame: after 8 weeks of treatment ]The Frontal Systems Behavior Scale.Raw scores are converted to T-Scores using published norms. T-Scores have a mean of 50 and a standard deviation of 10. T-scores less than or equal to 64 are within the average range. T-scores equal to or greater than 65 are indicative of a clinically significant problem. Higher scores indicate greater problem severity.
Secondary Outcome Measures:
- Lawton Brody Activities of Daily Living Questionnaire [ Time Frame: at baseline ]Caregiver reported performance of personal and instrumental activities of daily living (ADLs. There are 6 personal ADLs (i.e. dressing, grooming, eating, etc) and 8 instrumental ADLs (i.e. managing finances, transportation, food preparation) which are assessed. Each item is awarded 2 points for fully independent, 1 point for minimal or moderate support required, and 0 points for full support. Maximum score for independence with all personal and instrumental ADL's is 28.
- The Direct Assessment of Functional Status Scale [ Time Frame: at baseline ]A direct, examiner observed assessment of basic and instrumental activities of daily living. Participants are awarded points for correct performance of activities. Raw score is used for statistical comparison.
- Zarit Burden Inventory [ Time Frame: at baseline ]Measure of Caregiver Burden. Caregiver rates each item assessing burden on a 0 to 4 point scale with higher numbers reflecting more frequent occurence of the behavior or feeling being assessed.
